Hello. I have a honda hrb216 hxaa mower with a gcv160 engine. I can't figure out how to fine tune the engine speed. Below is a photo of the control plate/governor spring area. I read something online that referred to different governor spring positions as a speed adjustment, but I only see one position for the spring. Is there a screw adjustment somewhere that I am missing?
Thanks a lot. I think the owner's manual has these instructions or something similar. I will check this again. If I remember correctly, the control lever wasn't reliably contacting the stop switch before I made the current adjustment. Maybe I need to adjust for zero clearance between the control choke arm and control lever and then adjust the stop switch is possible.
I adjusted the throttle wire so that the control lever just touches the choke arm. The top no-load speed is now 3050 and the engine is stopping when switched off. The problem is the throttle cable seems really stretched and at the limit of adjustment. Probably needs to be replaced at some point.
